# service iptables save The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.
出错信息如上所示
解决方案:
首先停止防火墙
systemctl stop firewalld
systemctl mask firewalld
然后安装iptables-services
yum install iptables-services
设置开机启动防火墙
systemctl enable iptables
可以使用下面命令管理iptables
systemctl [stop|start|restart] iptables
这时可以保存防火墙规则了
service iptables save
or
/usr/libexec/iptables/iptables.init save
如果你之后要使用firewall的话：
执行命令，即可实现取消服务的锁定
# systemctl unmask firewalld
下次需要锁定该服务时执行
# systemctl mask firewalld
